NH4I will completely dissolve in ammonium and iodide ions: of which I-is neutral and NH4+ is quite a weak acid (pKa = 9.25). (The molar standard solution of NH4I will have pH approx. 4.6).
Best Answer: NH4 is not a stable chemical on its own. It is a cation and it is written as NH4+ and needs a negatively-charged counter ion. The ion is called Ammonium. Ammonia is NH3 Ammonium hydroxide is NH4OH but dissociates in water as NH4+ and OH-Ammonium bromide is NH4Br.
